IMPROVEMENT IN HILLSIDE-FLOWS.

Specification forming part of Letters Patent No. 9,519, dated January 4, 1853.

To all whom it may concern:

Be it known that SAMUEL HALL, late of the borough of Manchester, in the county of Allegheny and Stateot' Pennsylvania, deceased, did in his lifetime invent a new and Improved Hillside-Plow 5 and We, JOHN C. BIDWELL and JOHN HALL, of Pittsburg, county of Allegheny, and State of Pennsylvania, administrators of the estate of the aforesaid SAMUEL HALL, deceased, do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, making part of this specification.

Figure l is a side elevation of the plow; and Fig. 2 is a side elevation of the same, a por' tion being removed and the mold-boards being spread apart to show some of the parts more clearly.

Like letters designate corresponding parts in both figures.

The plow is constructed with a landside, (J, of the usual form for a double plow, and provided with two plowshares, pointing in opposite directions. Two mold-boards, E F, are hinged to said landside by projecting ears I l on the under side both of the mold-boards and landside, so that they will readily turn forward and backward when required. The respective hinges of each mold-board are at a considerable distance from each other, thus allowing free play to either mold-board without disturbing the other, as well as for other pur poses hereinafter set forth. The edges 8 s of each mold-board fit into and rest in the nearest grooves, n p, in the landside when the mold'board is turned down for plowing, and each mold-board is further supported bya projection, m, at a considerable distance from the hinges thereof, which projection is shaped so as to fit into the groove n, which is situated farthest from the axis of its moldboard. When either mold-board is turned down its hinged dles B attached, turns on said pivot, so that; its

direction can at any time be readily reversed. A clasp, e, is attached to the beam, so as to vibrate forward and backward, and is operated by a rod, f, hinged thereto, and extending back near one of the handles B of the plow, so that the plowman may reach its rear end, h, and control its action. Said clasp e fits accurately over projections d (1 upon the landside, near the socket B, and when thus fitting over oneof said projections prevents theplow-beam turning on the plow; but when said clasp is pushed forward away from said projections the beam is free to turn either way. Itis secured upon its projection while plowing by a notch, "i, on the handle f, which notch or shoulder is pressed down below the edge of a loop, g, on the side of the handle B.

X'Vhen plowing the mold-boards are turned, the one back and the other down, as shown in Fig. 1. As soon as the other end of the furrow is gained the handle or rod f is raised and pushed forward, which movement disengages the clasp e from its projection d, thereby setting the beam A free. The team is then brought round, reversing the position of said beam, the plow remaining in the meantime unmoved. The beam is then secured in that position by drawing back the rod f again and depressing the shoulder 13 behind the loop g, thereby bringing the clasp 6 over the other projection, d. The team then movesforward, when the mold-boards E F are immediately reversed by the pressure of the furrow.

The peculiar advantages from the above-described manncr of constructing and arranging the mold-boards E F consist especially in the greater strength and durability gained by the mold-board resting on the landside not by the hinges l I alone, but also upon the edges 8 s and the projection m, which is placed as far as practicable from the hinges of the mold board, and consequently supports it and prevents inuch strain upon the hinges by the leverage of the other end, whereas by any other construction there can be no support to the mold-board at a distance from its hinges, and, by consequence, the great pressure of the furrow upon the projecting end of the mold-board renders it very liable to be taken at the hinges.
